For a somewhat different aspect of Jasper Maskelyne's life, you (he) might want to consider Anne Davenport and John Salisse's St. George's Hall: Behind the Scenes at England's Home of Mystery (Magic Words, 2001)

Thank you, Michael. I'm sorry it's taken me this long to reply, but I appreciate your prompt response. I haven't found the book you mentioned yet, but as an employee of the Pasadena Public Library, I expect I'll manage.

This book will be about Mr. Maskelyne's career as a performing magician in England, though, and not specifically about his wartime efforts? I'm still interested, but my main focus is on his work with the military.

Do you know where Geniis Magic Journal might be located? Is it an online source, or print publication? Since you're posting from Australia, and you mention that Mr. Stokes is also from Australia, I'm guessing it may be published Down Under.
